Trevor, this is what Scott Cadillac sent me on the list, and I'm using it now (with the exception that I'm not reading anything about the file from a database, so I get the values for Content-Type, Content-Length, etc from other places.
Try the site Scott mentions below:

Hi Henning,
You are missing a couple of important bits like the 'encodeResults' variable
setting to prevent your binary characters from being converted to HTML
entities and the 'Content-Length' of the download file. Also, I find that
for secure downloads adding the <@userreferencecookie> prevents Witango from
issueing a new UserReference which could break your user session.
<@assign name="encodeResults" scope="local" value="false">
<@assign name="httpHeader"
scope="local"
value="Content-Type: <@var
local$resultSet[1,MimeType]><@crlf>Content-Length: <@var
local$resultSet[1,FileSize]><@crlf>Content-Disposition: inline;
filename=<@dq><@var
local$resultSet[1,Filename]><@dq><@crlf><@userreferencecookie><@crlf>">
Then where you do your output, it should look like the following to clean
out any whitespace that Witango will sometimes through in between the HTTP
Header and the content:
<@PURGERESULTS><@VAR local$dlfile ENCODING="NONE">
I wrote a short article about this kind of procedure and there is a sample
file for download.

Hope this helps. Cheers...

Subject: Witango-Talk: return protected file
Is there a way for Tango to return a file (contents unknown - may be a word doc or an excel file, etc.) from a protected location to a user? The application is such that there would be a directory on the webserver containing files that must not be accessed through a URL but may need to be returned to a user within the application that has rights to view the files. Windows based installation using IE.
Regards
Trevor Green
